Accidental diesel in Rotax 912
I accidentally added 20 lt of diesel to 20 lt of avgas in the tank and flew a circuit at the end of which the oil pressure had fallen to the red line and the temperature was rising rapidly. After the tank, lines and carburettors had been flushed and the oil changed the cruising oil pressure dropped from 4 to 2 bar, the oil consumption rose from 1 lt per 22 hrs (45 ml per hour) to 1 lt per 6 hrs (167 ml per hour) and there was some debris in the filter, whereas previously there had been none. Subsequently the differential cylinder pressures proved to be below the Rotax minimum of 65 psi on a reference of 86 psi. I understand that the introduction of diesel can reduce the amount of blow by gasses and thus reduce the return of oil to the reservoir.
I should much appreciate any advice or information about similar experiences experienced by other Rotax owners.
